How will climate change affect U.S. crop yields?

As the UN climate conference kicks off in Egypt, food and agriculture are central to negotiations for the first time. More severe droughts, warmer temperatures and heavier rainfall fueled by climate change are making it harder than ever for the world’s one billion farmers to grow food and fiber. While some farms and regions are more vulnerable than others, climate change will affect farmers everywhere.

Here in the U.S., where farmers have a long history of steadily increasing yields, climate change will likely cause crop productivity gains to stall — or even reverse — as soon as 2030.

New report provides a science roadmap for natural climate solutions

Natural climate solutions, such as reforestation and wetland restoration, can help slow climate change and increase resilience in the face of climate impacts we can’t avoid.

These approaches have substantial and growing support from bipartisan lawmakers, the private sector and environmental nonprofits. However, big questions remain: Where are these strategies most effective? To what extent can they meaningfully remove and reduce greenhouse gases? How will increased drought, fire and pest outbreaks impact their ability to stave off climate change?

My perspectives on how we can inspire the next generation of Black climate leaders.

By Arianna Mackey, Environmental Defense Fund (EDF) Summer 2022 Intern

I became aware of my community’s lack of environmental awareness at a very young age. Growing up in the Hampton Roads area of Virginia, my family and I visited the Nauticus museum often. One afternoon, after spending time in the flooding exhibit, I explained to my mom that due to increased flooding, Virginia Beach would be inhabitable in the future, with standing water reaching the front door following a storm. She brushed me off by saying it was an “over-exaggeration” and our community was fine. That encounter piqued my interest in environmentalism. Read More »

World Food Day has come and gone, with food security still out of reach for people and planet

Every October, the global community comes together to celebrate the founding of the United Nations Food and Agriculture Organization as World Food Day. Taking stock, it is plain to see just how far we still have to go to achieve the FAO’s founding mission to defeat hunger and improve nutrition and food security for the planet.

The obstacles to achieving this goal are many and complex: the COVID-19 pandemic, the war in Ukraine, and the ongoing challenges of conflict, water shortages, flooding, and rising food costs are just a few. However, they all share one thing in common: they are exacerbated by the existential threat of climate change.

With less than a month to go before the 27th United Nations Climate Change Conference (COP 27) in Egypt, world leaders must consider the importance of addressing food insecurity as a part of solving the climate crisis.

Crop-switching in the megadrought: Can guayule help Arizona farmers use less water?

This year, farmers in Pinal County, Arizona, will lose two-thirds of their irrigation water from the Colorado River because of a historic shortage declaration triggered by the driest period in more than 1,000 years. And within two years, they will be completely cut off from the Colorado River.

Some farmers are responding by fallowing fields. Others are selling their land to solar companies. And then there’s Will Thelander, a farmer who partnered with EDF, Bridgestone Americas and the University of Arizona to test a new crop that uses half as much water as the alfalfa he previously grew.

Crop-switching to a desert shrub called guayule used to produce rubber is one of just many strategies that will be needed in Arizona and other regions to adapt to water scarcity and maintain agricultural economies in a new era of aridification. However, it’s not nearly as simple as just planting different seeds in the ground.

Capturing water from atmospheric rivers will help build drought resilience in California. Here’s how.

This blog was co-authored by Nicole Schmidt, a recent graduate from UC Santa Barbara’s Bren School of Environmental Science and Management.

Several locations in California set all-time 24-hour rainfall records this past weekend when an atmospheric river delivered much needed precipitation as the majority of the state remains in extreme drought conditions.

In Sacramento, this wettest day on record followed the longest consecutive dry spell on record amid California’s second driest year.

As scientists have been predicting, climate change is causing more dramatic extremes in weather — both wet and dry — and that pendulum swung very dramatically to the wet side over the weekend.

Consequently, it’s critical we prepare now to capture and store water during these shorter, intense wet periods so that more water is available during the inevitable increasingly severe drought years ahead. Read More »

3 acciones críticas para la equidad del agua en las comunidades latinas de California — ¡apúrense!

Es una paradoja penosa para California, la quinta economía más grande del mundo: Algunos de los mismos trabajadores agrícolas que recogen nuestra comida no pueden beber un vaso de agua limpia, o ni siquiera tener agua, en fregadero de la cocina.

He trabajado en temas de justicia ambiental en EDF durante los últimos seis años, y he tenido la oportunidad de hablar con algunos de estos trabajadores esenciales, muchos de los cuales provienen de países de habla hispana como yo.

A medida que el Mes de la Herencia Hispana llega a su fin, la sequía en California avanza obstinadamente. Es importante reconocer cuán importantes son estos trabajadores del campo que cosechan los alimentos en todo nuestro estado y más allá.

Más allá del reconocimiento que se merecen los trabajadores del campo, los líderes estatales y locales deben tomar al menos tres pasos críticos para eliminar esta paradoja:

3 critical actions for water equity in California’s Latino communities – ¡apúrense!

Lea en español

It is a painful paradox for California, the world’s fifth-largest economy: Some of the very same farmworkers who pick our food can’t drink a glass of clean water — or any water in some cases — from their kitchen sink.

While working on environmental justice issues at EDF for the past six years, I have had the opportunity to talk with some of these essential workers, many of whom come from Spanish-speaking countries like me.

As Hispanic Heritage Month comes to a close while the drought in California stubbornly marches on, it’s important to recognize how instrumental these farmworkers are to providing food throughout our state and beyond.

But besides recognition, state and local leaders need to take at least three critical steps to eliminate this paradox:

Climate change is destabilizing the Colorado River Basin. Where do we go from here?

In June, a portion of my neighborhood in Flagstaff, Arizona, was put on pre-evacuation notice due to a nearby wildfire. A few weeks later, storms dumped heavy rains over a burn scar from a 2019 fire that caused destructive floods through parts of town. So far, this summer has been our third-wettest monsoon season on record, a complete contrast from our two driest monsoon seasons on record in 2019 and 2020.

These extremes are just a few local examples of the havoc that climate change is causing around the world. Here in the West, we are now in uncharted territory with the first-ever shortage declaration on the Colorado River.

3 ways this accounting platform will help California groundwater agencies transition to sustainable supplies

This blog is co-authored by Tara Moran, president and CEO of the California Water Data Consortium.

As California grapples with another drought, farmers and water agencies will again lean on groundwater to offset declines in surface water supplies stemming from paltry snowmelt and corresponding low reservoirs and river flows.

However, there is at least one major difference from the last drought: Since then, more than 250 groundwater agencies have been created and have spent the last several years compiling data on their region’s groundwater supply and demand. To comply with the Sustainable Groundwater Management Act (SGMA) many groundwater agencies are now considering new tools to use this data to support groundwater management decisions.

Today, Environmental Defense Fund, the California Department of Water Resources, the State Water Resources Control Board and the California Water Data Consortium announced a partnership to scale one of these tools: an open-source water accounting platform. Here are three reasons why this announcement is so important. Read More »
